The Dalai Lama's comments followed the meeting of US President Donald Trump and North Korean leader Kim Jong Un. They signed a document in which the American president pledged "security guarantees" for Pyongyang, and the Korean confirmed his commitment on complete denuclearization of the Korean Peninsula.
